The Petite Trotte à Léon’s itinerary includes technical passages which are much more difficult compared to those of most other trail running races (e.g. the UTMB®). It requires a very good knowledge of the mountain environment. Some passages may present objective dangers: steep slopes, risk of stone falls, very narrow paths, crossing scree slopes or glaciers, no paths or clearly marked trails... The route is NOT WAY-MARKED and is often FAR FROM INHABITED ZONES. It is to be completed in total autonomy between life-bases and partner huts. For their own safety, participants must be able to master navigation with a GPS. They also must be able to read a map, use a compass and an altimeter. They must imperatively race as a team (less than 50m from each other). They must also be able to confront naturally difficult conditions.



UTMB Group organizes the PTL® in collaboration with les Amis de l'UTMB association. It is directed by a Race Committee whose decisions are final.


Participating in UTMB® events implies the explicit and unreserved acceptance of these regulations, the ethics of the event and any instructions sent by the organization to the participants.


  • Participants in the PTL® must complete the itinerary without going over the time limit. It is not considered as a competitive event and as such does not give official finishing rankings.
  • It is open to teams of men, women or mixed of 2 or 3 people. The total number of runners will be limited to 300.
  • Teams are strictly inseparable. In the case of an abandonment of a runner in a team of 3, the 2 remaining runners can only continue after ensuring that their team member has been left at a life-base or refuge and if they have the authorisation of the race HQ. In the case of the abandonment of a runner in a team of 2, both runners have to stop.
  • The route is to be completed in autonomy, the teams managing their supplies and their rest time as they wish. Along the route, runners may find:
    • Life bases (i.e. a main aid stations) open 24/24, where participants may sleep and eat. They will also get their spare bags. Runners have unlimited acces to beds and bunks, but they still must leave the life base before the cut-off time.
    • Partner refuges/mountain huts, open 24/24, where competitors may sleep - for free, according to availability - and a eat (in exchange for a meal ticket*. Runners might be able to use beds and bunks only for a limited time, according to availability.
    • The services offered by any other non-partner hut are at to be paid for by the participants, while respecting the hut's schedule and the peace of its other clients
  • Assistance is not allowed at any point along the course. It is strictly forbidden throughout the entire course, including aid stations, partner refuges, when passing through villages or along roads, at the risk of immediate disqualification.
  • No assistance is allowed along the route.

*In the limit of the 4 meal tickets distributed.



To register, each team has to present a file proving each team member's previous experience. Technical experience in the mountain environment, sporting history as well as team motivation will be taken in to account. A draw may be organized in case of too many pre-registered participants. If all the teams of 3 selected after the examination of the files do not allow to reach the limit of 300 runners, a draw will be made among the teams of 2. If the total number of teams of 3 selected after the examination of the files exceeds the limit of 300 runners, a draw will be made among the teams of 3 and no team of 2 will be selected. The PTL® is open to all people born in or before 2004 (categories espoir to veteran).

The 2024 PTL® starts from Chamonix and travels through middle and high mountain environments foraround 300 kilometers with about 25 000 meters elevation gain. The start is at 08am on, Monday, August 26th 2024 from the Place du Triangle de l'Amitié of Chamonix ; finishers will be welcomed in place du Triangle de l'Amitié in Chamonix until 16:30, September 01, 2024 and cut-off time for finishing is 152:30 hours.


Each race-bib is issued individually to each competitor upon the presentation of an ID with photo and after having signed a commitment on their honor to keep the mandatory equipment with them at all times during the race.

It must be presented at any checks along the race route. In Chamonix, the race-bib is “the pass” necessary to access shuttle buses, buses, aid stations, rest areas, showers, and sack drop-off and pick-up points. In addition to each race-bib, each team member will receive an ID bracelet, to be worn on the wrist throughout the race.


A GPS tracker is supplied to each team. This tracker allows the organization to track the progress of the team and ensure that it respects the route. This information will be available on the internet. The positioning of the tracker on the bag recommended by the organization must be strictly respected.


Cut-off times are defined for the life-bases and any other area judged by the organization to be imperative for reasons of security. They are calculated so that participants can make it to the finish line within the maximum permitted time of hours (152:30).

The organization ensures the repatriation of runners (who abandon or who fail to meet the time barrier) from every check point with a cut-off time.. In the case of abandonment at all other points along the route, without exception, runners must organize their return by their own means. The organization will ensure the repatriation to Chamonix of the bags of runners who have withdrawn, on condition that their withdrawal has been registered. The delay of the repatriation depends on logistical constraints and the organization cannot guarantee that all bags are brought to Chamonix before the end of the race.


Any complaint must be sent by email, within 10 days after the end of the event.


If necessary, the organization reserves the right to modify at any time the routes, starting times, cut-off times, the position of aid stations and medical stations, and any other aspect related to the smooth running of the events.

In the event of cancellation decided less than 15 days before departure or in the event of interruption of the race, for any reason whatsoever, no registration refund will be made.


Civil liability The organization takes out a third party insurance for the duration of the event. This civil liability insurance guarantees the financial consequences of its liability, that of its employees and that of the participants.
